Look At Photos, Anyone Know What Causes This?

Its called a halo.

Produced by unusual atmospheric conditions - usually from too much pollution in the air I think.

Anyway - there's allready a thread about this in the Pattaya sub forum.

Cheers,

As I'm sure you can imagine the Thais have attached numerous superstitions to this phenomena. Some years ago a number of our staff galloped off to the temple on seeing a halo around the sun.

But not just the Thais, there is a reference in Suetonius about such a halo being seen as a portent of victory to the army of Julius Caesar during one of his campaigns in Gaul.

That would suggest then that while pollution might be a cause, it is not the only cause. Unless we have evidence of large scale atmospheric pollution at the time of the Gallic Wars. (Burning hovels perhaps?!)

That looks like a halo as already described but under certain atmospheric conditions you can get two rainbows, one a full circle, around the sun. On the full circle, if you get a real good one, you will see five (I think - but maybe seven) bright points of light.

A truly wonderous thing is atmospherics.

JUST PHOTOGRAPHED THE SUN AND IT LOOKS WIERED TODAY, ANYONE KNOW OWT ABOUT IT?post-23892-1180676515_thumb.jpgpost-23892-1180676605_thumb.jpg

Yes its 'Halo's' caused by the diffraction of the sunlight through water vapour droplets in the upper atmosphere, causing the same effect as a rainbow except it produces circular rainbows, not the half moon type that we normally see from the ground.

Seen the same in the UK and also at night with the moon as the light, only this time it was even more spectacular as it was formed by ice crystals in the upper atmosphere which gave a very ghostly spreading halo.

notice how the bangkok post also photographed the TRT building set with the halo in the background? :o

if u want to know what thais make of it...put 2 and 2 together....doomsday for TRT....doomsday for thai politics...etc etc. so to dramatise the effect they take a photo of TRT building (who have just faced the biggest bad 'luck'/mishap)

Obviously, this is NOT a halo. It is a Platonic Perfect Shape, observed on Earth to remind us all that Santa will be coming soon. Six more shopping months till Christmas, folks!

It's often caused by ice crystals in the atmosphere. Usually means rain is in the offing.

marine lore calls for rain in 24hrs ...........

Heavy rain was forecast for today. Didn't eventuate though, clear skies all around..

Cheers,

Soundman.
